do you think i can use this valve on a 55 gal boil kettel? I have no idea who made it. it came on a wine fermenter. it has a black rubber gasket inside but not really any kind of makers mark.
That appears to be a butterfly valve. They are typically rather pricey. I would be concerned about damaging the rubber seat exposing it to high temperatures. Protect it from excessive heat and it should work OK, but might be better to use a ball valve and save the butterfly valve for use on something else like a conical fermenter maybe.
